  • PROCESS FOR SCAVENGING HYDROGEN SULFIDE PRESENT IN A FLUID STREAM
    Publication number: 20170044444
    Abstract: A process for scavenging hydrogen sulfide present in a fluid stream is provided. The process includes treating the fluid stream with a polytriazine, wherein the polytriazine converts the hydrogen sulfide to a corresponding thiol or thioether derivative, thereby reducing the amount of hydrogen sulfide present in the fluid stream.
